Verbena plant named &#39;Lan Redtwo&#39;

ABSTRACT

A  verbena  cultivar particularly distinguished by red flowers, broad leaves and tolerance to powdery mildew.

GENUS AND SPECIES

Verbena hybrida

VARIETY DENOMINATION

‘Lan Redtwo’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of verbena, botanically known as Verbena hybrida, and hereinafter referred to by the cultivar name ‘Lan Redtwo’. The new cultivar originated from a hybridization made in the year 2002 in Gilroy, Calif. The female parent was ‘1371-1’, a red proprietary verbena line (unpatented), while the male parent was ‘1352-1’, a purple proprietary verbena line (unpatented).

The new cultivar was created in 2002 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif. and Andijk, The Netherlands over a two-and-a-half-year period. The plant has also been trialed at Gilroy, Calif., Litchfield, Mich. and Andijk, The Netherlands. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

DESCRIPTION OF PHOTOGRAPH

This new verbena plant is illustrated by the accompanying photograph which shows overall plant habit, flowers, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Lan Redtwo’. The data which define these characteristics were collected from asexual reproductions carried out in Gilroy, Calif. The plant history was taken on 5-month-old plants grown in one-gallon pots, in a poly-covered greenhouse. Color readings were taken in the greenhouse in the late winter season under natural light. Color references are primarily to the RHS Colour Chart of The Royal Horticultural Society of London (RHS) (2001 edition). Texture description details were observed under a dissecting microscope.
